UFS campuses are transforming into research instruments while simultaneously improving campus operations through the Smart Grid initiative.

Imagine living in a smart home. Imagine monitoring your household’s electricity usage via an integrated system that would notify you of your daily electricity use, peak usage times, and tariffs and consumption at the location of the house. As a user, you would be able to take advantage of such information in order to manage your resources in a more efficient manner. This is just one example of what a Smart Grid can do.

The University of the Free State’s (UFS) Faculty of Natural and Agricultural Sciences has teamed up with the Department of University Estates to drive our very own Smart Grid initiative that is transforming the university’s power network into one with full control and monitoring. “A Smart Grid allows for resource optimisation and asset protection, especially in times like these,” said Nicolaas Esterhuysen, Director of Engineering Services. 

Why is it important for our university to have a Smart Grid?
Dr Jacques Maritz, Lecturer of Engineering Sciences at the Faculty, considers a Smart Grid the natural evolution of power grids in the era of Big Data, IoT and Machine Learning. Resources such as electricity, water and steam can now be monitored and controlled to promote savings and the protection of valuable infrastructure. “Aiming towards Smart Grid status, the UFS will improve resource service-delivery to its staff and students, while sculpting a digital twin of its campus’s power grid, consumer network and resource generators,” he added.
  
How will a Smart Grid improve student success?
The integrity, sustainability and continuous supply of energy directly affects the academic project on all three campuses. The implementation of a Smart Grid could allow improved service delivery and reaction time when any utility is interrupted, as well as maintaining the valuable infrastructure that serves the UFS community.

In what way does a Smart Grid improve the lives of staff members?
According to Dr Maritz  and Esterhuysen: “A Smart Grid will support staff to perform their teaching and research duties in a seamless manner, continuously optimising the energy that they consume to enable full comfort and reliability in energy supply, whilst simultaneously generating savings in energy and preventing wastage.”

The UFS already boasts most of the fundamental building blocks associated with the Smart Grid initiative, especially focusing on monitoring, grid protection, centralised and decentralised solar PV generation and software platforms to serve all these domains. However, to integrate all of these domains into one digital real-time paradigm will be a first for the UFS.

Some examples of the UFS smart grid applications currently in practice
Real-time remote monitoring and control that focuses on the following:
- We are able to detect power outages and don’t have to rely on customer complaints. This enables faster response time and fault identification, thus less downtime and an increase in reliability;
- Solar plant generation; 
- Monitoring our standby generation fleet; 
Identifying usage patterns and saving thereof;
Benchmarking buildings in terms of application usage, area or occupancy to determine energy efficiency and identify savings; and condition-based preventive maintenance that will increase reliability while saving costs.

From peasant to president; from Samora Machel to Cahora Bassa

When the plane crashed in Mbuzini, the entire country was submerged in a profound grieving.

This is how Prof Allen Isaacman, Regents Professor of History at the University of Minnesota, described the effect President Samora Machel’s death in 1986 had on Mozambique. In a public lecture, Prof Isaacman spoke about the man, Samora Machel, and the influences that shaped Machel’s life. The event, recently hosted by the UFS International Studies Group on the Bloemfontein Campus, was part of the Stanley Trapido Seminar Programme.

Samora Machel: from peasant to president
Born in 1933 into a peasant family, Machel was allowed to advance only to the third grade in school. “And yet,” Prof Isaacman said, “he became a very prominent local peasant intellectual and ultimately one of the most significant critics of Portuguese colonialism and colonial capitalism.” Machel had a great sense of human agency and firmly believed that one is not a mere victim of circumstances. “You were born into a world, but you can change it,” Prof Isaacman explained Machel’s conviction.

From herding cattle in Chokwe, to working as male nurse, Machel went on to become the leader of the Liberation Front of Mozambique (Frelimo) and ultimately the president of his country. To this day, not only does he “capture the imagination of the Mozambican people and South Africans, but is considered one the great leaders of that moment in African history,” Prof Isaacman concluded his lecture.

Displacement, and the Delusion of Development: Cahora Bassa and Its Legacies in Mozambique, 1965–2007
Later in the day, Profs Allen and Barbara Isaacman discussed their book: ‘Displacement, and the Delusion of Development: Cahora Bassa and Its Legacies in Mozambique, 1965–2007’ at the Archives for Contemporary Affairs. As authors of the book, they investigate the history and legacies of one of Africa's largest dams, Cahora Bassa, which was built in Mozambique by the Portuguese in the late 1960s and early 1970s.

The dam was constructed under conditions of war and inaugurated after independence by a government led by Frelimo. The dam has since operated continuously, although, for many years, much of its electricity was not exported or used because armed rebels had destroyed many high voltage power line pillars. Since the end of the armed conflict in 1992, power lines have been rebuilt, and Cahora Bassa has provided electricity again, primarily to South Africa, though increasingly to the national Mozambican grid as well.
